Participate in the liquidation on DDEX to earn money 💰💰💰

Margin positions will be liquidated if the collateral rate too low. When a liquidation occurs, the borrowers' assets are sold off in a form of a dutch auction to repay the loan. This bot help you bid the auction when profitable.

The bot uses an arbitrage strategy: Sell collateral on DDEX immediately after receive it from an auction. For example:

• An auction sell 10ETH at price 160USDT
• The bot buy 10ETH
• The bot sell 10ETH on ddex at price 170USDT
• Earn 10*170-10*160=100USDT

You need to prepare some asset(e.g. ETH, USDT, DAI) in your DDEX spot trading balance.
